Abstract : A unique frequency-modulated continuous wave (FM-CW) radar has been developed at the Naval Electronics Laboratory Center, San Diego, California which has a combination of great sensitivity and ultra-high resolution for the detection of atmospheric structures. In particular, it routinely detects and displays the fine scale features of many, if not most, inversions in the lower two kilometers of the clear atmosphere. The observations made to date are highly meaningful in a variety of meteorological contexts; for example, (1) in understanding the mechanisms of turbulence generation in hydrostatically stable layers in general, and more specifically, (2) in revealing the origins of clear air turbulence, (3) in detecting CAT, (4) in advancing our knowledge of convection and the boundary layer, (5) in studying the structure and metamorphosis of inversions, (6) in tropospheric radio scatter propagation and (7) in air pollution. The present report discusses the relevance of the new observations to most of these topics. In addition it deals with certain new aspects of dot angel echoes from insects. (Author)
